How arbitrage works
Convert each outcome’s best odds into an implied chance and add them up. If the total is under 100%, splitting your stake in proportion to those chances returns the same amount whatever happens — more than you staked.
Arbs are rare and short-lived, and books may limit accounts that bet them. Always check each book’s rules first.
